A high-performance adaptive radiative cooler comprising a multilayer-filter VO 2 -based Fabry–Pérot (FP) cavity is proposed. The bottom FP has four layers, /NaCl/PVC/Ag. Based on the phase transition of , average emissivity in transparent window can be switched from 3.7% to 96.3%. Additionally, also adjusted with external strain PVC layer, providing another way attain desired cooling effect. An upper filter included block most solar radiation and provide transmittance 96.7% atmospheric window. At high temperature, emitter automatically activates cooling. net power up 156.4 W⋅m −2 at an ambient temperature 303 K. Our still exhibits stable selective different incident angles heat transfer coefficients. low deactivates, decreases only 3.8%. Therefore, our work not provides new insights into design coolers but advances development intelligent thermal management.
